Studied sedimentary section, located in the southern part of the Moravian Karst ca 10 km east of Brno, exposes several loess and paleosol layers. The topmost bed of the sequence is formed by 0.5 m thick brown soil underlain by 3.5 m thick loess containing weekly developed thin soil. Mineral magnetic characteristics were diagnose using different methods (both volume and frequency dependent magnetic susceptibilities, temperature dependent magnetic susceptibility, IRM, SIRM) with the aim to explain how climatic and post-depositional processes affected mineral magnetic assemblage of both loess and soil material.
